Abstract: PURPOSE:To reduce the weight of a permanent magnet by a method in which plural cores are integrated on the end portion of the side to be touched by the permanent magnet e.g., a rare earth-cobalt-based magnet. CONSTITUTION:One end of a core 9'' of internal magnet type is shaped into a flat form in such a way that it can wholly contact with a permanent magnet 10'', and thereby the contact area can be increased beyond the conventional ones and the used of magnetic materials having smaller magnetic flux density is made possible. A wide range of magnetic materials can be chosen. To avoid the demagnetization of the magnet 10'' by inverse excitation by the coil 8'', the use of magnets having greater 1Hc is much safer, and also since the thickness of the magnet is desired to be thinner as much as possible from the standpoint of operational characteristics, an SmCO2-based rare earth-Co magnet of an energy product of 18MGOe is used. The weight of the permanent magnet can be greatly reduced as compared with the conventional ones.

Title: Method and device for gas leak detection
Inventor: NISHIYAMA MASANOBU
IPC: G01M3/02
Filed: 1986-06-30
Abstract: PURPOSE:To securely detect a gas leak even in a space which is opened by simple constitution by monitoring the temperature variation of piping itself which supply gas and its periphery and the temperature difference between two measurement points at the two measurement points. CONSTITUTION:If gaseous silane, for example, leaks at a piping joint part 2 of a gas pipe 1 and burns naturally, the heat produced by the combustion is conducted by air and the gas pipe 1 to spread in the periphery. Then the detection signal of a temperature sensor 4 varies and the comparison signal of a comparative arithmetic circuit 7 also varies at the stage where the heat is conducted to a heat conduction part 6 closest to the gas leak position (piping joint part 2). Consequently, an alarm board 9 detects the natural combustion due to the gas leak at the periphery of the heat conduction part 6 because the detection signal and comparison signal supplied to a comparing circuit do not coincide with a reference temperature distribution and temperature difference distribution data. Then, an alarm buzzer is made to sound and an alarm lamp is made to illuminate, indicating the gas leak.
